which are connected into outer heads 152 and 1551 of thowater mcasurer21.

`The outer head 152 is secured on the end of the main cylinder 154 by anut 155. `An

-adj usting holt 156' is threaded through the (center oi'vthe. head 152and a measuring` scale 157 is secured to the head, a ring 158 y'onthebolt 156 cooperating with a scale 159 to `indicz'tte the exact positionof the bolt y 15G and thereafter the position of a main piston 160 whichslides freelyin the cylinder 154. The main piston 160 consists of a.nain piston body 161, cup leathers 162 and 1611 separated h v awasher164. andyclamped a nut 165. and a bolt 166 secured The head 153 issecured ou an `inner head casting 167, this inner head casting haring abore 168 in which an auxiliary piston 1G!) is free to slide. This pistonconsists of cup leathers 170 and 171 secured on the body' 172 by meansof a bolt 173 and' a. lock nut 174, a spacing washer 17 .ri serving toseparate them. A projection '178 'fs centrally formed on the end of thebody 172. rl`he"borc 168 'is closed by a washer having a central opening181 an opening 183 formed therein, the space between the. washer 180 and182 forming a valve rhambeii' 184 inwhich a ralve-185 is pla-ced, thevalve consisting oli rubber washers '1% and 1.87 secured on a body 188.A `rompi-essieu` spring 18) is placedbetwcen the body IHS and the washer182 `orthc purpose of normally holding the` washer 186 againstrthewasher 180, thereby closing the .drole 181. fluted stem 190 formed onthc body 185 projects into the hole 181 for the purpose ot' guiding thevalve 185, and a ll uted stem 191` projects into theihole `183 for thesaine purpose. Tater from a (tank or other source of vsupply is`conducted through a pipc`192 into the valve chamber-184, this waterpassing freely through the opening 183 into the interior of the cylinder154 when the parts are in the position shown in Fig. 9. A. water outletpipe `193communi.- eates with the interior. of the bore 168 below thewasher 180, this pipe 193 eommunicab ing `with the pipe which supplieswater jto the interior of -t le washer, this water passing downwardlythrough the Washer to .the `film nozzle 23.'i

pen communication is'provided between `the 'valvecharnber 181` and theinterior of the cylinder lrithrough openings 195 and 196. The opening195 is controlled by a body`198, the needle valve 197 having a stein 199passing through packing 200 which is compressed by a follower 201 whichis also threaded in the needle valve body 198.

The method of ,operation is as follows:

When the various apparatus is not in op# eration, the handle 114v andthe plug 24 are turned to the inoperative position, the foot valvesupply pipe 9S beingin open communication with the pipe 115 through thegroovey in the tapered plug 113 and 'through the opening 116. t the sametime the open ing 118 is vin open communicationwith the outer airthrough the opening 120 in thetapered plug 113 and through vthe exhaustport 121. Air pressure is therefore exerted against the bottom of themain piston 42. The main piston 42 is therefore held in the extremeupper end of the cylinder, the end of the piston contacting with theupper stop 80 and holding the main valve 70 to its ex' treme upperposition, this position of the various parts being hereinaftercalledposition 1 and shown diagrammatically in Fig. 10. In this position theexhaust openings 88 are closed by the piston leather 74, the openings 89and 90 communicating with the interior` of the sleeve 58 which is inopen communication with the interior yof the main cylinder 22. Theopenings 90 `a re in open communication with theiouterneedle' valve19,7" threaded in a needle valve no tendency for the parts to move, themain piston 42 being at the extreme t'op of the r cylinder 22, the mainvalve 7 0 being at the extreme top of the sleeve 58, and the auxiliaryvalve body 107 being in the 4 position shown in Fi 3. With the parts inthis position the 1m nozzle 23 is in the ositi'on shown at A in Fig. 1,being entire y above the basket and out of the way.

Since the pipes 150 and 151 are iii open communication through the pipe130 with the cavity 90 which is in open communication with die"u verair, there is no air pressure in the ef Jine ends of the water measurerand Ythe valve 185 is seated against the 'washer 180, thereby shuttingof communication between the pipes 192-and 193. No water therefore flowsthrough the pipes .193 and consequently no water is supplied to theopening 61 in the top of the washer. Water.

is, however, free to low through the openings 195 and 196 into theinterior of the cylinder 154 of the water measurer. This water ressureforces vthe main I:piston body 161 into the position shown in ig. 9, theamount of water taken in to the cylinder 154 being re lated by adjustingthe bolt 156.

' hen it is desired to put the machine into operation the plug :cock 24is thrown into the operative position. This connects the opening 118with the opening 116, therefore admitting air pressure from the pipe 115into the space between the cup leathers 108 and 109, pressure beingmaintained in this 4space during theentire time the washer is inoperation. At the same time the openings 120 are thrown out of enagement with the port 121. Pressure is still maintained, however, inthepipe 98 so that the upward pressure on the main piston 42 is constant.

Owing to the large` diameter of the mainpiston pipe 41 the efective areaon the bottom' of the piston is very considerably less than the area onthe top so that whenever an equal air pressure is placed on both the topand bottom ofthe main piston 42 this piston is forced downwardly.Whenever the plug cock is thrown into the operative .position the airunderspressure from the space between the cup leathers 108 and 109-flows through the opening 111 into the pressure cavity 86 and fromthence through the open'- ings 90 into the interior of the sleeve 58 andinto the interior of the main cylinder 22.v The air pressure acting onthe top of the main piston 42 tends to force the main piston downwardly,at the same time the air pressure entering the opening through theopenings 89` and the cavity 85 is transmitted connects the openings 122with the air presbeing 'and the constant air sure between the cupleathers 108 and 109, and this a-ir preure flows downwardly through theopenings 123 and 124 to -the port 125. The parts at this time are inwhatwill hereinafter be called position 2, 7. as shown in Fig. 11, theauxiliary valve being at its extreme right hand position, themain valvebeing at its extreme upper tion; and the main piston just startingdownwardly. As the main pistonstarts down- 7i, wardly it uncovers theport 125 thereby opening an additional channel to` the top of thecylinder 22, the parts at this time being in what may be called position3, as shown in Fig. 12. The main piston 42 continues to auf move evenafter the cup leathers 74 over the openings 90, thereby shutting of theair which has been iiowing through these openings into the cylinder, asair is still opening 124 and the ports 122. As the main piston 42 nearsthe end of its stroke the auxiliary valve 70 is actuated by the mainpiston body striking the stop 81, the auxil iary valve body beingcarried down into the "tol position shownin Fi 2 and the iilm nozzlebeing in the positionv C as shown in Fig..1. The parts are thenin thefourth position, -as shown in Fi 13, the main piston beingl at theextreme ower limit of the stroke, the 96 auxiliary valve being still atits extreme right hand position, and the main valve being at its extremebottom position. With the parts in this position, as shown in Fig. 2,the ports 90 are completely isolated by the cup leathers 73 and '74, theportsl 88 and 89 being inl open communication through the space betweenthe cup leathers 72 and; 3. The air underpressure is therefore free to,escape from the extreme left hand eiid of the'v 105 auxiliary valvecylinder, this airescaping throu h the exhaust ports 87 into the outerair. e 'air pressure between the cup leathers 108 and.109 alwaystends'toforce the'valve 107 to the left hand position since the culeathers 108 are 4larger in diameter than t e cup leathers 109. 'Theauxilio. valve therefore moves to its original or le handy position, theparts then assuming position 5, as shown in Fig. 14. In this position115 the port 125 is connectedto the outer air through the openings 124,123, the ports 122, and the exhaust port 112. Pressure is thereforerelieved from above the mainpiston 42 ressur'e beneath this pistonstarts it upw y. The main piston does not, however, to the extreme top1of the cylinder du'e to e fact that the stop is so placed that it .isstruck and the main valve is moved upwardly until the cup leather 73passes over the-openings 89,.there supplied through the port 125, theelico 'wardly. The main piston 42 moves downwardly until it strikes thestop 81 pullingv the auxiliary valve into position 4*, alr pressure thenworking to throw the parte into the potqutomatically shut ofi' the flowof water ail) sition 5, Vand the cycle being repeated through positions6 and 7 tti-the original -position 4.

It is thus seemthat the main piston reciprocatcs up and down actuatingthe main yvalve 70 which in turn opens and closes ports 'to actuate theauxiliary' valve 107, this auxiliary valve in turn controlling themovement of the main piston. This continues until the plug cock 24 isthrown into the inoperative position. This connects the various parts asAhas been previously explained, the main piston being iorced up to itsextreme upper position and the parts occupying position 1. It will thusbe seen that the' film nozzle 2? is reciprocated u and down from theposition shown at B inFig. l'to the position C,

When the-plug Vcock 24 is operated the. film nozzle 23 is lifted totheposition A and remains' there` until Ythe machine is again put ixioration. Y

, e function of the water n'n-asurer '21 is tothe charge of'fellmass assoon as a certain predetermined amount of water has-passed through themeasurer.

The water-.measureroperates in the following manner: The various partsbeing in the position shown in'Fig. 9, the plug cock 24 is thrown intothe operating position and the washer .20 start-s to reciprocatethrowing the water in a thin film over the charge of fellmass in thecentrifugal separator as it moves up and down. As soon as the plug cock24 is thrown into the operating posit-ion air pressure is supplied tothe water measurer through thepipe 130 and througl'i the pipes 150 and151. A constant .water pressure is maintained in the pipe 192, air

4150 and 151, the pressure per square inch ofthe air supplied throughthe pipes 150 and .151Hbeing eonsiderablyin excess ofthe pressure persquare inch ofthe Water supplied .4 through the pipe 192. As soon as theair is 'in Fig. 9, the projection 178 strikin,f r against the end of thefluted stem 190 and forcing the gvalve 185 upward into such a positionthat asf the rubber Washerj187 strikes against the 4pressure heiligsupplied through the pipes ythe main cylinder 154 below the main pistonwater pressurc'tluauxiliary piston 169 is held in this position. waterflowing through thc pipe 192 into the valve chamber 184 and through theflutes in the luted stcni 190 and the opening 181 to the pipe 193. thispipe being;r connected to the coupling 63 so that the water fiowsdownwardly through the openf ing 61 into the interior of' the washer andthrough the pipe B5 Vto the film nozzle 23. At the saine time that theair pressure acts on the auxiliary piston 169 through the pipe 151 itacts on the main piston 160 through the pipe 150, this main piston being`forced downwardlyv by the action of the air pressure thereon. As theauxiliary piston 169 acts almost instantly the opening 183 is'practically instantly closed so that the waterl in 160 is almostimmediately trapped. this water escaping from the main cylinder 154through the openings 195 and 196.' The rate of flow through theseopenings is controlled by the needle valve 197, this needle valve beingset so that the How of water is very much restricted and so that themain piston 160 moves relatively slowly. During the movement of themainpiston the auxiliary piston 169 holds the valve 185 in its raisedposition, water flowing through the pipe 192 to the pipe 193and from thepipe 19? to the washer as previously explained. As the main piston 1GOcontinues to I nove downwardly it strikes against the end ot the flutedstem 191 pushing the valve 185 downwardly and forcing the rubber washer18T from its seat so that water is free to flow through the. opening1,83 around the l'uted stem 191. As themainpiston continues its movementit forces the washer 1,86 against the washer 180 thereby Vclosing theopening 181 so that' the How of water between the pipes 192 and 193 isentirely shut-oil' and water ceases to flow through the film nozzle 23.The. washer will continue to reciprocate without water being supplieduntil the. plug cock 24 is thrown to the inoperative position. thusthrowing the film nozzle 28 into position A free from the'centrifugalseparator. At the same time the air supply in the pipes 15() and 151 isreleased and the water pressure acting against the main piston 160 andowing through the opening 183 forces the main piston 160 into its upperposition as shown in Fig. 9. The parts of the measurer and the washerare then in their in` operative or initial position and the cycle may berepeated.

The time requiredpfor the main piston 160 to close the. valve 185 andshutoff the How of water between the pipes192 and 193 may be regulatedby means 'of tlie`screw-156', this screw regulating the amount of watertaken 'into the niain cylinder 154 and therefore regulating the timerequired to expel this water. The time for the main piston 160 to closethe valve 185 may also be regulated by means of the needle valve 197,this needle valve regulating the rate of flow of the water through theopenings 195 and l196 and thereby controlling the time required for thepiston 160 to complete'its motion.
